To aZZ whom it may concern'.-

' B e it known that I, FREDERICK PARADIS,

of Chicago, Cookcounty, andState of Illinois,

have invented certainlnew and-usei'ullm-y provementsin BatteryfGhutes,of which the.

following is a specification.

This invention relates-to improvements in storage-receptacles, andrefers more speciiicthe trade as batteryfchutes.

ally to an' improved receptacle adapted for the storage ofelectricbatteries,'especially when l used underground, and commouly'known in,The objects of the invention are provide a simple economicalconstruction which is ladapted to be readily'sealed hermeticall'y, so

as to effectually protect'the battery from weather and'againstdeterioration by evaporation,` oxidation, &c.'; to-provide' a `construc-.tionlwhich may be installed undergroundwthout danger of access ofmoisture or'dirtA tothe battery andto which access may be readily hadwithoutmoving the 'receptacle from its .placeof-installation; tolprovide improved meaus for edecting the sealing of the opening throughwhich the conductors con#y uected with Athe batteryelements extend,

-whereby the open-ing and'clo'sing of the receptaole does; not aiec't ordestroy the seallng of said conductor-opening; to provide alconstruction which while sealedl against 'acl cess of air'and moisturenevertheless provides-- for the relief of pressure incase batteriesbeemployed which generate anl internal presf sure in thereceptacle5 and ingeneral to pro-- vide, a simple, improved, and eiicientcon struction ofthe character referred to.

To.

more frequently than it is necessary to remove the batteries bodily, itbecomes important to provide means for leading the conductors outthrough'the wall ofthe receptacle in such manner that' they are notdisturbed by the opening and closing of the .re-

ceptaole. It is also' a feature of 'great im`v portance th-at thechute-be kept'hermetically closed, both'in order to prevent access ofair and moisture thereto and, further, to prevent l evaporation oftheiiuids ofthebatteries,whch evaporation rapidly destroys the eiciencyof the present Yinvention means of attaining only' maintains the thisend I provide upon the interior .of tlie mam recept-aciea smallsealingreceptacleor cup 14, which is so locatcdthat the con.

An ordinarypadlock may be employed to secure .the staplestogether by passing the. hasp of the lock'therethrough inthe usualmanner.

the present invention is ,n.'ot only extremely cheap to mannfacture,.but provides perfect protection for the battery against moisture and'the weather'and against unauthorized tampering.
